If you are finishing a square-edged step and need the edge to survive traffic without becoming a trip hazard, this is the profile that does it. The Effector A34 is a 35mm x 35mm anodised aluminium angle that wraps the front of the tread and the top of the riser in one piece, giving you a hard-wearing nose where the floor covering would otherwise wear through first. It suits a fresh installation as well as a refurbishment where the step edge is already chipped or worn. Specify it screw-fixed, with the plugs and screws supplied, or self-adhesive where drilling is not an option, in five anodised finishes and two lengths.
The manufacturer states that the A34 is ribbed on the tread and the riser, not only across the top. That matters on a stair. The tread ribs give you grip underfoot, and the riser ribs catch the light differently from the surrounding finish, so the step edge reads as a defined line instead of disappearing into the floor covering. On a flight where every step looks the same, that visual definition does as much work as the texture does.
The finish is an anodised layer grown into the surface of the aluminium rather than a coating sitting on top of it. It will not chip away from the leading edge the way a painted or powder-coated trim does, which is the failure you normally see first on a stair nose after a couple of winters of grit and footfall.
A 35 x 35 angle covers the vulnerable corner in a single piece, so no joint sits where the load lands. It also conceals a step edge that is already damaged, which is usually why a refurbishment specifies a nosing at all.
The manufacturer lists the profile as compatible with wood, laminate, tile and vinyl stair surfaces, and its own fitting photographs show it run over carpet. In practice that covers most internal flights: domestic staircases, office and communal stairwells, retail and showroom steps, and refurbishment work in schools and healthcare buildings where a worn edge needs covering without closing the staircase. The 900mm length suits a single step; the 2.7m is cut down on site.

Length. 900mm covers a single standard-width domestic step; 2.7m is the run length and is normally cut into three. Order by total linear metres and allow for the cuts, rather than counting steps.
Fixing. The screw-fixed version arrives with plugs and screws and is the one to specify for a public or commercial stair, anywhere the nosing will take a trolley wheel, or on a substrate you cannot rely on for adhesion. The self-adhesive version uses a factory-applied adhesive and suits a domestic refurbishment, a rented property, or any step you would rather not drill. Both share the same profile and the same five finishes, so the choice is purely about how it is held down.
Finish. Silver and Inox read as neutral metal. Gold and Champagne warm the edge. Black gives the strongest contrast against a pale covering, which is the one to pick if step definition is the point.
Measure the width of the step and cut the profile with a hacksaw or a mitre saw fitted with a non-ferrous blade, then deburr the cut end. For the screw-fixed version, drill and plug the substrate and countersink the screws into the pre-formed holes. For the self-adhesive version the substrate must be clean, dry and sound – dust or a loose surface is what causes an adhesive nosing to lift at the nose within a few months. Clean with a damp cloth and a neutral detergent. Avoid abrasive pads and solvent cleaners on the anodised surface; both will dull it.
Only the fixing method. The screw-fixed version is supplied with plugs and screws and seats into pre-formed holes along the tread. The self-adhesive version has a factory-applied adhesive backing and needs no drilling. The extrusion, the dimensions and the five finishes are identical across both.
No slip resistance figure – no pendulum value, R rating or PTV – is published for this line by the manufacturer, so we do not quote one. The anti-slip function comes from the ribbed tread and riser. If a project needs a tested and certified figure, ask us and we will point you at a profile that has one.
Yes. Both lengths cut readily with a hacksaw or a mitre saw with a non-ferrous blade. The 2.7m length is normally cut into three domestic-width steps. Deburr the cut end before fitting so the edge is not left sharp.
We specify it for internal use. The manufacturer does not publish an external rating for the profile, and while anodised aluminium resists corrosion well, we will not claim a weather performance that has not been stated. For exterior steps ask us for a profile rated for the job.
Select your length, finish and fixing method above; each combination is priced individually. Order by total linear metres and allow for cutting waste. If you need a quantity for a whole building, or want to check a finish against a floor sample first, contact us and we will help you specify it.

Arrived snug in its parcel! Once installed, this edge guard feels rock-solid, even when the stairs see a bunch of foot traffic on rainy days. The aluminum stair nosing blends seamlessly with the tiles for a polished look up close, and no ones slipping here any time soon!

Had my doubts at first about the durability during shipping, but everything arrived well-secured in sturdy packaging. Used it on our concrete steps in a busy warehouse and it’s been a solid addition. If we ever need aluminium stair nosing again, wouldnt hesitate to go for this one.

Put it on the seaside steps last spring, and several months later its still looking sharp despite constant wear. Grains of sand havent scratched its surface, which was a pleasant surprise. Cant beat that durability for the cost!

Got this for tidying up the edge of our office marble stairs, and the aluminium angle really pulls the look together without shouting too loud. For those wondering if its worth it, trust me, the stair nosing just makes everything seem much more finished and sleek—and isnt that what were all aiming for? Easy to attach and no hassle to clean if someone scuffs it.

Brilliant craftsmanship. Installed the aluminium nosing on our garden stairs and cutting it to length was straightforward—you wont need more than a saw. The nifty fit along each step helps keep the surface sleek without any snags, despite loads of foot traffic from family barbecues all summer long.
